A battery protection apparatus designed to sit next to a battery cell with at least one electrode. It includes two lead plates for connecting to the cell's electrode(s). A pad unit provides conductive pads for connecting external devices to the battery. A device unit has electronic components to protect the battery cell. Wiring connects the lead plates, pad unit, and device unit. An insulator covers parts of the lead plates, pad unit, device unit, and wiring, ensuring the device unit and wiring are not exposed.
2. The apparatus of claim 1 , further comprising a temperature protection device that is adapted to be interposed between the second lead plate and the bare cell of the battery.
The battery protection apparatus as described, further incorporates a temperature protection device positioned between one of the lead plates and the battery cell to monitor the temperature of the battery. This device is added to protect the battery from overheating and potential damage.
3. The apparatus of claim 2 , wherein the temperature protection device includes an electrode tab that is adapted to be connected to a first electrode of the bare cell of the battery.
In the battery protection apparatus that includes a temperature protection device between a lead plate and the battery cell, the temperature protection device has an electrode tab that is connected to an electrode of the battery cell. This electrode tab facilitates temperature sensing directly from the cell's electrode.
4. The apparatus of claim 3 , wherein the insulator includes an opening that is positioned to expose the electrode tab of the temperature protection device in a location adjacent the first electrode of the bare cell of the battery.
In the battery protection apparatus featuring a temperature protection device with an electrode tab connected to the battery cell, the insulator has an opening positioned to expose the electrode tab. This opening allows access to the temperature sensor's electrode tab, enabling external monitoring or connection near the battery cell's electrode without compromising the insulation of other components.
5. The apparatus of claim 1 , wherein the plurality of conductive pads of the pad unit are electrically connected to the lead plates via the device unit and the wiring wherein the insulator fixes the first and second electrode, the pad unit, the device unit and the wiring in position with respect to each other.
In the battery protection apparatus, the conductive pads are electrically connected to the lead plates via the device unit and wiring. The insulator secures the lead plates, pad unit, device unit, and wiring, maintaining their relative positions. This fixed arrangement ensures reliable electrical connections and prevents movement or damage to the components within the apparatus.
6. The apparatus of claim 5 , wherein a first pad is connected directly to the first lead plate and is connected to the second lead plate via the device unit.
Considering the battery protection apparatus where the conductive pads are electrically connected to the lead plates via the device unit and wiring, one pad is directly connected to one lead plate and connected to the other lead plate through the device unit. This configuration allows for specific current paths and voltage regulation through the protection circuitry.
7. The apparatus of claim 5 , wherein a second pad is electrically connected to the second lead plate by the device unit and the wiring.
Within the battery protection apparatus where the conductive pads are electrically connected to the lead plates via the device unit and wiring, another pad is electrically connected to the second lead plate by the device unit and wiring. This creates a specific circuit path that utilizes the protection features of the device unit before connecting to the second lead plate.
8. The apparatus of claim 1 , wherein the device unit comprises a resistor, capacitor, varistor and a switching device.
In the battery protection apparatus, the device unit, which protects the battery cell, contains electronic components including a resistor, capacitor, varistor, and a switching device. These components work together to provide overcurrent, overvoltage, and over-temperature protection for the battery.
9. The apparatus of claim 1 , further comprising a plurality of support members that extend outward from the device unit, the pad unit and the first and second lead plates so as to extend into the insulator.
The battery protection apparatus additionally has multiple support members that extend from the device unit, pad unit, and lead plates into the insulator. These support members provide structural integrity and secure the components within the encapsulating insulator.
10. The apparatus of claim 9 , wherein the plurality of support members have outer ends that are exposed outside of the insulator.
Regarding the battery protection apparatus with support members extending into the insulator, the outer ends of these support members are exposed outside the insulator. This exposure may facilitate heat dissipation or provide additional mechanical support points.
